The invention provides for the management and protection of excess lengths o f utility cables in extendable semi-trailers. Utility cables are affixed to th e front and rear sections of an extendable semi-trailer and are threaded through a protective carrier that can bend in only one direction. This directionally restrained carrier rests within a channel that shields the carrier and the cables from wear and tear and which constrains the bending of the carrier to one trans-channel turn. As the trailer is extended, the front and rear sections of the trailer and therefore the ends of the cables and carrier will move relative to one another. The cables and carrier move within the channel from a generally "U"-shaped pattern to a generally "J"-shaped pattern as the traile r moves from the retracted to the extended position.
